A new precision measurement of the proton's electric polarizability has confirmed an unexplained bump in the data. The proton's electric polarizability shows how susceptible the proton is to ...

New force distributions revealed by the calculations, on top of the probability map of finding a quark in the proton. Scientists have now mapped the forces acting inside a proton, showing in ...

Much is already known about the proton’s electric charge; it arises because of the electrically charged quarks whizzing around inside the proton. This motion defines the proton’s ‘electric charge ...

The small but ubiquitous proton serves as a foundation for the bulk of the visible matter in the universe. It abides at the very heart of matter, giving rise to everything we see around us as it ...

CHAMPAIGN, Ill. — An international team of nuclear physicists has determined that particles called strange quarks do, indeed, contribute to the ordinary properties of the proton. Quarks are subatomic ...

Scientists develop groundbreaking theory for calculating what’s happening inside a proton travelling at the speed of light. For more than 2,000 years, scientists thought the atom was the smallest ...
